Our company just put this out, full MoQ support for MediaMTX with 200-300ms latency - demo at https://moq.wink.co/moq-player.html

GitHub: https://github.com/winkmichael/mediamtx-moq

We implemented both WebTransport (for browsers) and native QUIC (for server-to-server) after discovering browsers block raw QUIC. Works today in Chrome/Edge, integrates with existing RTMP/RTSP streams in MediaMTX.
